you get what you pay for
i've owned three pairs of leatts over the course of 5 years, two of them broke from being used so much/ tossed around in my gear bag a lot, but the most recent of my leatts is the dbx pro carbon and coming from someone who does a lot of crashing and thrashing, these hold up great. The carbon obviously increases it's stiffness and strength, and decreases its weight. I'm very happy with all of the leatt braces in their lineup, but this one is by far my favorite. Of course, the one big drawback is the price, but again, you get what you pay for.
